why don't you ask your clients what they meant by that instead of asking here? Even if you do get real answers here you're not guarnateed that they are what your clients are thinking.
Personally if I acted on advice here and then was later questioned by the clients about why I included certain features and the answer I had to give was "That was what they suggested on alt.home.repair" I'd feel pretty stupid and unprofessional.
but that's just me. ml
